Flash flood advisory issued

A typhoon warning remains in effect for Agrihan, Pagan and Alamagan. On Guam a flash flood advisory was issued by the National Weather Service due to heavy rainfall. It is in effect until 6 p.m., Monday.

Residents living in areas prone to flooding should be prepared.

The Offices of Guam Homeland Security and Civil Defense issued these reminders:

Clear drainage areas and un-block clogged storm drains in your area to minimize the change of flooding.

Avoid walking or driving through flood water.

Just 6 inches of moving water can knock you down, and 2 feet of water can sweep your vehicle away.

If there is a chance of flash flooding, move immediately to higher ground. Do not wait for alerts or warnings.

If floodwaters rise around your car but the water is not moving, abandon the car and move to higher ground. Do not leave the car and enter moving water as the current may be carrying debris from your surroundings.

Avoid hiking, camping or parking along streams, rivers, and creeks during heavy rainfall. These areas could flood quickly and with little or no warning.
